Hello I m 19 years old, I went on a hard diet to lose weight but after I lost 8kgs I started having some bowel movement changes, like I m having a frequent constipation, and a feeling that I can t clean my bowel completely, I ve searched on google and all I found was colon cancer so I got very worried, tho I have no rectal bleeding or fatigue, and I haven t lost more weight since I regulated my diet what should I do? Should I go for a test ?
